IWMSDiagnosticEvent Interface
The IWMSDiagnosticEvent interface contains information about a specific event notice that you can use to diagnose problems concerning the configuration of the server or the status of a plug-in.
In addition to the methods inherited from IDispatch, the IWMSDiagnosticEvent interface exposes the following methods.
Method |
Description |
|---|---|
get_AdditionalInfo |
Retrieves the text message associated with the event notice. |
get_ErrorCode |
Retrieves the HRESULT return code associated with the event notice. |
get_Name |
Retrieves the name of the plug-in or server limit associated with the event notice. |
get_NumberOfOccurrences |
Retrieves the number of times the event notice has occurred. |
get_PublishingPointName |
Retrieves the name of the publishing point that raised the event notice. |
get_Time |
Retrieves the date and time of the event notice. |
get_Type |
Retrieves an enumeration value indicating the type of the event notice. |
Example
The following example illustrates how to retrieve a pointer to an IWMSDiagnosticEvent interface.
#include <windows.h>
#include <atlbase.h> // Includes CComVariant.
#include "wmsserver.h"
// Declare variables and interfaces.
IWMSServer *pServer;
IWMSDiagnosticEvents *pDiagnosticEvents;
IWMSDiagnosticEvent *pDiagnosticEvent;
HRESULT hr;
CComVariant varIndex;
long lCount;
// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
NULL,
CLSCTX_ALL,
IID_IWMSServer,
(void **)&pServer);
if (FAILED(hr)) goto EXIT;
// Retrieve a pointer to the IWMSDiagnosticEvents
// interface and retrieve the total count of events.
hr = pServer->get_DiagnosticEvents(&pDiagnosticEvents);
if (FAILED(hr)) goto EXIT;
hr = pDiagnosticEvents->get_Count(&lCount);
if (FAILED(hr)) goto EXIT;
// Retrieve information about each diagnostic event.
for (long x = 0; x < lCount; x++)
{
varIndex = x;
hr = pDiagnosticEvents->get_Item(varIndex, &pDiagnosticEvent);
if (FAILED(hr)) goto EXIT;
// Release temporary COM objects.
pDiagnosticEvent->Release();
}
EXIT:
// TODO: Release temporary COM objects and uninitialize COM.
